Today natural diamond gemstones have real challengers

Millions of individuals like diamond gemstones, only some of these people can afford them. As a result, there is demand for gemstones of the same properties as natural diamond stones.

Rhinestone is also known as diamante is made of rock crystal, acrylic or glass. These are called Strass after Georg Strass, a jeweller who coated the lower part of the glass for it to look likewise natural diamond. Indeed, the Strass is like diamond glass, as a result sometimes strass-diamond is taken as real diamond gemstone. Only those clients who do not have a cognizance of how real stone can look like can be shafted, others - without a chance.

Crystal doesn't have features so charachteristic of real diamond, such as firmness, refractory property and endurance. Cause is that these gemstones have different kind and structure. Surely, its price is by far cheaper consequently everybody can purchase it, but it won't be a real stone.

A very favorite diamond replacement in jewelry world is Cubic Zirconia. CZ is isometric, just like diamond is. This prop helps it to look like a 100% real gem. But Cubic Zirconia is man-made material that's why to fabric crystals and in order to let these remain solid at standard temperatures stabilizer is always mandatory. Typically ytrrium or calcium can play the role of stabilizers, but the amount of these elements is estimated by each manufacturer on an individual basis. So, the matter is that the oxides are included in the finished product.

It makes the stone weight more than real diamond. Moreover the CZ's dispersion is much higher as compared to diamond. That's why, it is that easy to cheat an amateur and convince him CZ is a real one, but cubic zirkonia will for sure fail the break testing - just hit the stone with smth. very heavy, strong as real diamond.

Other kinds of simulants will not succeed in both thermal test or destructive one, even in either of tests. It seems nothing can turn the diamond low-priced for real people. All the same, in year 1954 a serious competitor to manually mined gemstone was created - simulated gemstone. It varies from all other diamond gemstone simulants by props, conditions of synthesis, composition and physical structure. Man-made gemstone is grown in a laboratory under HPHT conditions, that imitate natural environmental circumstances needed for diamond formation.

Synthetic gemstone consists of 100% the same ingredient as real diamond - carbon. Lab-grown gems possess the same characteristics as real gemstones: chemical, optical and physical. these have the solidity, glistering effect and longevity as natural gems. Additionally, these cost less and can be found. It's possible to either order them on-line or at any jewellery shop.

For very exacting clients lab grown stones can be bought in various colors, yellow, blue, green, pink that are extremely expensive and rare when found in natural conditions. They are also can be purchased as loose diamond gemstones or as diamond jewellery. So, today "real" diamonds became bargain-priced.
